get your foot in the door of a company/industry
To 'get your foot in the door' refers to taking the first step in doing or achieving something. This expression comes from the image of a salesperson going door-to-door - if they got their foot in the door it makes it difficult for people to refuse them or send them away. This expression is usually used to talk about making a connection with someone that can lead to opportunities in the future or to entering employment at a low level with the intention of moving up in the company. This is an idiomatic expression used in both social and professional contexts.
